You're kinda being ignorant right now. T.I was never close to Eminem's level, sales wise. Jay-Z had no singles, once again. BP3 sold a lot (a lot being still LESS than Relapse) because it had Empire State of Mind (which was bigger than any Relapse single).
The most sold Hip Hop albums since 2009 are something like Recovery and Relapse. I think it sold even more than Take Care or Carter 4.
But we'll have this debate again when he'll go platinum.
Justin Timberlake is a veteran, by the way. You could also consider Rihanna as one.
